My present invention provides an eXtremeportion a that adapts it to be detachably ly simple and highly efficient resilient wheel but securely held in position by a retaining adapted for general use on vehicles but esflange 12 and by clamping lugs 13.V VThe pecially adapted for automobile service and, flanges l12 are shown as formed integrally generally stated, the invention consists of with the several felly sections 7 and the lugs 55 the novel devices and combinations of devices 13 are detachably held to the felly structure and arrangement of parts hereinafter deby the outer nut-equipped bolts l9.

This rim 10 has acontracted central the respective heads 17 and shoes 19 in cen- 1300 tered or intermediate positions and in which positions the said parts will remain, when the hub structure is concentric to the felly and rim structure.

The resilience ofthe wheels is due to the following actions:

When a load is Vplaced on 'the hub fstructure, it will move downward in respect tothe felly and rim structure1 and will be resisted by springs -26 and the friction between `the shoes 19 and the outer fiangesof-the`fe1lysec tions 7. The chief function of the springs QA is to keep the shoes 19 frictionally'engaged with the section 7 It is evident that downward movement of the hub structure or any movement of the '-hub structure out of concentricity with the felly structure will be laccomplished only by Ycausing sliding movements of the several shoes 19 against the felly sections. These shoes, therefore, act in conjunction with the springs to give -resilience to the'wheeland said shoes further act more vor less'as vshock absorbers. The-structureabove described is such'that grease may bekept well-lubricated so that the wear vwill bereducedto a minimum and noise will be eliminated.

What I claim-is:

g1, A `resilient wheelrim comprising normally concentric hub and felly f structures, the; latter being made up of hollow 'segmental sections, shoes movable circumferentially under'friotionwithin said felly sections, :heads Aconnected to said shoes for sliding movements therewith, and 4having radially extended stems, vspokes securedtosaidhub structure andtelescopically-engaging the stems ofsaid Y heads,` opposing springs reacting-against lthe Yends of said fellysections Mandagainst jsaid respective heads and springs re-actingfagainst said? heads and A felly sections with a force -pressing 'said shoes Ainto frictional engage- Cment` with the respective' felly`4 sections.
